Definitions

  • This invention relates generally to the alignment of window shades within window casements and, more specifically, to the alignment of the Silhouette shade system developed and marketed by Hunter Douglas Company; the invention is also useful with other types of shades.
  • window covering systems have to provide a satisfactory and proper geometric fit to the window openings which they cover. While problems associated with an imperfect fit may be less critical for some window covering systems, e.g., draperies, other systems including blinds or shades require rather strict compliance with geometric fit standards. A shade that does not fit properly in its window opening may be aesthetically deficient and therefore unacceptable. The problem is exacerbated if a poorly fitting shade affects the proper functioning of the shade. For example, a shade may be so skewed within the window opening that one side of the shade may bind against one side of the window opening while the other side of the shade may be separated from the other side of the window opening, leaving a wide, uncovered gap that precludes total privacy.
  • the shade may be skewed to the extent that it cannot be moved within its window opening without application of excessive force, which may cause damage to the shade or its mechanical components.
  • Roller type window shades are probably most vulnerable to proper geometric fit problems. A major reason is that even the slightest initial imperfection of geometric configuration of the shade within its window opening will be multiplied with every rotation of the shade. Errors in the geometry of the shade system, when added to window geometry imperfections and/or installation errors, result in unsightly shade systems with functioning problems as well. These aesthetic and function problems are quite annoying for the user, particularly if present in some modern, more decorative systems, such as the Silhouette Shading system developed by the Hunter Douglas Company.
  • the Silhouette system offers several desirable features, both functional and decorative, that are not found in the conventional, uncomplicated spring wound roller shade, but present difficult geometric fit considerations with extremely close tolerances that must be addressed if a satisfactory installation is to be accomplished.
  • U. S. Patent No. 971 ,414 issued to M. J. Smith on September 27, 1910 discloses a Swinging Support For Window Shades.
  • the device is an additional bracket to which a standard shade may be affixed, which bracket permits arcuate and linear movement.
  • the present invention provides for permanent adjustment of chronic imperfections of fit in permanently installed shades, particularly in shade systems where adjustment tolerances are extremely limited.
  • U. S. Patent No. 1 ,113,181 issued to G. Ardito on October 13, 1914 discloses an Adjustable Shade Support which provides for adjustable arcuate displacement of the shade roller from the window lintel.
  • the device is intended to adjustably displace the shade roller from the top of the window, for ventilation.
  • U. S. Patent No. 1 ,901,674 issued to N. Slobtkin on March 14, 1933 discloses an Adjustable Mounting For Window Shades.
  • the device provides a similar function to that of the devices of the Ardito and Hyland patents discussed above, but also provides a means of skewing the shade within the window opening.
  • the means are unlike those of the present invention.
  • U. S. Patent No. 4,979,775 issued to O. Klose on December 25, 1990 discloses an Axially Displaceable Window Shade for Windshield Or The Like.
  • a stationary threaded shaft is provided about which a shade roller revolves and traverses to provide a constant lateral position of the shade depending upon the amount the shade is drawn.
  • No means for adjusting the lateral travel is disclosed, other than providing different thread pitch.
  • one of the objects of the present invention is to provide an improved means of angular and lateral system adjustment which is directly applicable to the Silhouette shade manufactured by Hunter Douglas Company, but which may also be applicable to other types of shades and shade systems.
  • Another of the objects of the present invention is to provide an improved means for increasing the starting gap where needed and for the alteration of the magnitude and geometry of the forces and moments acting on the system by transferring the shade actuating mechanism from one end of the shade roller to the opposite end, thus to modify, in a desirable fashion, the lateral and angular position of the shade within the window opening.
  • Yet another of the objects of the present invention is to control the manner in which the shade is wound upon the shade roller, to minimize spiralling and control the magnitude of internal gaps between the edges of the shade and respective ends of the roller when the shade is rolled up and down.
  • Still another of the objects of the present invention is to provide a means by which a head rail of a window covering system may be torsionally biased in order to control the magnitude of external gaps between edges of the shade and respective edges of the window opening.

  • roller type window shades particularly the type of shade known as the Hunter Douglas Silhouette, but extendible to other shade types, to provide for the various angular and lateral adjustment of roller type window shades within a window frame.
  • FIGURE 1 shows the main components of the Silhouette shade assembly and the fundamental geometry of the external and internal gaps relevant to the shade adjustment procedures and devices.
  • the central roller 10 allows shade 20 to be rolled up or down with a weight of lower bar 30 attached to the bottom of the shade.
  • roller 10 is attached to end plates 60 and 70.
  • a single cord 51 of the roller actuating mechanism 50 is used to roll shade 20 up and down.
  • the entire Silhouette assembly is attached to the lintel L by the means of the mounting bracket 80 (not shown in FIG.1 for clarity) attached to the central housing 90 (again not shown) that connects both end plates 60 and 70 and covers the front of roller 10.
  • any roller-based window covering system may experience difficulties with the control of the shade rolling process. Generally, it is expected that the shade should provide even coverage of the window opening.
  • one edge of the shade will be closer to the corresponding window opening than the opposite shade edge, and in fact may even bind or interfere with the side of the window opening.
  • the resulting wrinkles in the generally planar sheet material of the shade are unsightly, and the corresponding gap at the opposite side precludes the privacy which may be desired when the shade is drawn.
  • FIG.1 shows in an exaggerated way for clarity, the essence of the adjustment need of the Silhouette shade.
  • the main idea is not to produce a geometrically "perfect” shade, but rather, to develop such a system of adjustments that can make the shade fit satisfactorily any, even imperfect, window openings.
  • Gap G is between the left edge 31 of low bar 30 and the edge of the wall W L .
  • Gap G 2 is between the right edge 32 of low bar 30 and the opposite edge of the wall W R .
  • Gap G 3 is between the internal face 61 of the left end plate and the left edge 21 of shade 20.
  • Gap G 4 is between the right edge 22 of shade 20 and the intemal face 52 of the roller actuating mechanism 50.
  • Roller end plug 40 is attached to the left end plate 60 whereas the roller actuating mechanism 50 is attached to the right end plate 70.
  • the original position of the shade 20 represented by the broken line positions of the edges 21a and 22a corresponds to the roller actuating mechanism 50 being on the left side and roller end plug 40 being on the right side of the roller 10.
  • FIG.1 demonstrates the result of the further adjustment procedure that corrected the spiral rolling of the shade by locally increasing the effective diameter of roller 10 from D, to D 2 by use of clip 100 attached to axial extension 11 of roller 10. As a result, shade 20 is in the new, corrected position represented by edges 21c and 22c.
  • FIGURES 2-4 demonstrate, in a schematic way, the three main conceptual ideas of geometric fit adjustment of the Silhouette shade, some of which are applicable to other window covering systems as well. These three ideas are labeled as Procedures A, B and C, respectively.
  • FIGURES 2a and 2b illustrate the effect of Procedure A which is reversal of the roller actuating mechanism 50 from left to right (or vice versa).
  • the result of such a procedure is generally control of external gaps G, and G 2 during the rolling process, (and to some extent also control of internal gaps G 3 and G 4 , as shown in FIG. 1).
  • Procedure A There are two main advantages of Procedure A. First, an extra gap is provided on the 'correct' side of the window (FIG. 2b), as roller actuating mechanism 50 makes the shade assembly asymmetrical. Second, by reversing mechanism 50 from one side (FIG. 2a) to another (FIG. 2b), a complex system of forces and moments acting on the shade system is altered and a slight desirable angular adjustment of shade 20 results.
  • FIGURES 3a and 3b illustrate the effect of Procedure B which is a modification of the rolling process by altering effective radius of rotation of the roller wherever necessary.
  • Procedure B primarily controls the magnitudes of the internal gaps G 3 and G 4 , but external gaps G, and G 2 are clearly also affected by this procedure.
  • FIGURE 4 illustrates the main idea behind the adjustment Procedure C which is torsional adjustment of a head rail 19 of any window covering system similar to shades or blinds that is permanently attached to the window lintel L (rather than to side walls W of the window opening). Due to a variety of reasons (such as a non- horizontal position of the lintel plane itself), vertical edges 23 and 24 of the shade 20 may not fit into the window opening in the wall or, at least, result in an undesirable effect of non-parallelness between shade 20 and the window wall edges W L or W R .
  • the head rail 19 (or in the case of Silhouette Shade system, central housing 90) needs to be adjusted.
  • the obvious restriction is that edge AB of head rail 19 cannot be altered as it would create some unacceptable gap between the top of head rail 19 and lintel L to which rail 19 is permanently attached.
  • dropping point D' to a new position D creates an invisible vertical gap G 5 that is causing shade edge 24' to take a new angular position 24 (in similar way edge 23' becomes edge 23) that creates a horizontal shift G 6 by displacing point E' into E at the bottom of the shade 20.
  • point D not seen from the front on one end of the head rail 19; points A, B and C remain all in their original positions. Therefore, head rail 19 needs to be torsionally adjusted so that original .
  • point D' takes a new position D that needs to be secured by means of some devices that would prevent reactive forces in head rail 19 to bring it back to its original position.
  • FIGURE 5 illustrates the roller part of the Hunter Douglas Silhouette shade assembly that incorporates a relatively complex extrusion as a central roller, sections of which are indicated as 10.
  • a left end plate 60 and right end plate 70 define the ends of the shade assembly; left and right end plates 60 and 70 will be seen to be mirror images of one another.
  • End plates 60 and 70 include central cylindrical bosses 62 and 72 to which a roller actuating mechanism 50 and opposite roller end plug 40 are secured by means of screws 55 and 45. Both roller actuating mechanism 50 and end plug 40 are provided with axial keyways 53, and 43. Keyways 53 and 43 cooperate with key 13 formed within the interior of roller 10. Roller actuating mechanism is a clutch with a non-movable part 56 and movable part 57 activated by cord 51. Non-movable part 56 is secured in its position by means of keyway 58 that cooperates with key 68 of left end plate 60. Roller end plug 40 rotates together with roller 10 and movable part 57 of roller actuating mechanism 50.
  • Shade 20 (not shown in FIG.5; see FIG. 1) is attached to roller 10, and it is rolling on roller 10 when shade 20 is rolled up manually by the means of cord 51.
  • Space available for shade 20 during the rolling process is limited by the internal face 52 of roller actuating mechanism 50 on one side and internal face 71 of right end plate 70 on the other side.
  • assembling roller 10 with roller actuating mechanism 50 on left side instead of assembling it on the right side determines in a unique way the geometry of both external gaps G. and G 2 as well as internal gaps G 3 and G 4 (see FIG.1) within any specific window opening which is commonly geometrically imperfect. Reversal of roller actuating mechanism 50 and roller end plug 40 creates a new geometry of the shade 20 within the window opening.
  • Procedure A provides both lateral and angular adjustment to the shade. It brings alteration of the previous system of forces and moments acting on the roller. As shade 20 tends to roll tighter on the side of roller actuating mechanism 50 than on the side of roller plug 40, some angular adjustment normally results from applying Procedure A.
  • a lateral adjustment results from the fact that the Silhouette shade is asymmetrical: roller actuating mechanism 50 is wider than plug 40; also tolerances for internal gaps G 3 and G 4 are not even, but in proportion 2:1 in favor of the gap on the side of the roller end plug 40.
  • Procedure A Application of Procedure A is easy and fast. First, the shade assembly needs to be removed from the window, then roller part of Silhouette needs to be disassembled. Roller actuating mechanism 50 needs to be installed upon the right end plate 70, and connected with end 16 of roller 10, see FIG.5. Keyway 58 will now cooperate with key 78. Screw 55 needs to be used for this installation.
  • roller end plug 40 needs to be assembled with left end plate 60 by the means of screw 45 and connected with end 15 of roller 10.
  • Central housing 90 (.not shown in FIG. 1 for clarity) will be assembled together with end plates 60 and 70, after which the Silhouette is ready to be put back to the window.
  • FIG. 1 shows also clip 100 and pad 110. Neither of these devices is related to
  • Procedure A Their role and function are explained in the next section.
  • C Detailed description of Procedure B: Controlling shade rolling process bv local adjustment of the effective radius of rotation of the roller
  • each roller can be represented by an effective radius of rotation R or diameter D.
  • Procedure B controls the rolling process, and can be used in two major applications.
  • the first application intends to eliminate spiral rolling and keep internal gaps G 3 and G 4 virtually constant throughout the rolling process.
  • the second application intends to allow some spiral rolling to occur if that was to benefit the overall fit of shade 20 within a specific, and often geometrically imperfect, window opening.
  • window covering systems among them Hunter Douglas Silhouette shade, use the concept of differential weights to provide an angular adjustment of shade rolling.
  • Fig. 1 shows weight 33 can be shifted from left to right or vice versa in order to angularly adjust rolling of shade 20 on roller 10, as needed. The inventor has found this device to have limited applicability and effectiveness.
  • Radius-altering devices are very simple, and can be used separately or together with other devices or procedures (such as Procedure A). They can also be used jointly with differential weight systems such as 33, with very good results.
  • Procedure B can be applied to any roller-based window covering systems or to other systems not related to window covering such as roller-based screens, or similar.
  • the main idea is to provide an asymmetrical modification of the effective radius of rotation to a specific place of roller 10. Sometimes the best effect can be accomplished by several modifying devices placed on roller 10 in such places that bring the best overall effect.
  • FIGURES 5 AND 6 show that the specific extrusion shape of roller 10 of the Hunter Douglas Silhouette shade includes axial extensions 11 and 14. Extensions such as 14 are provided for securing a shade 20 thereto, and/or providing separation for the components of shade from one another. Additional details, such as axial ridges 12 or 17 are also provided. These extensions 11 and 14 and ridges 12 and 17 may be used to advantage to modify the effective diameter D of roller 10.
  • clips 100 may be installed upon axial extension 11 (or 14) toward the left end 15 of roller 10.
  • the effective diameter D, of roller 10 is at least partially determined by outward extensions such as 11 , it will be seen that the addition of a clip 100 extending further outward from an extension 11 will serve to increase the effective diameter of at least that end 15 of roller 10 to a new diameter D 2 .
  • the resulting difference in effective diameters D 1 . and D 2 as shown in FIGURE 1 will result in a shade 20 wound thereupon closer to the left end 15 than it did before applying dip 100.
  • a more common application, however, for which Procedure B is primarily designated, is a process of correcting spiral rolling of shade 20 on roller 10, so that internal gaps G 3 and G 4 can be effectively controlled to remain virtually unchanged during the entire process of rolling shade 20 up.
  • dips 100 may be provided with a cooperating slot 101 which can be frictionally installed over extension 11, in the desired location.
  • a desired location of clip 100 on extension 11 of roller 10 can be easily maintained because of the reactive force from clip 100 acting on extension 11 of roller 10. It is important to note that movement of one or more clips 100 from left to right is easy, and thus a truly controlled, continuous adjustment of the effective radius of rotation is provided. The effect of the adjustment of the effective radius of rotation gradually diminishes as clip 100 is moved from left side 15 of roller 10 toward its center. When clip 100 is moved to the right side 16 of roller 10, the sign of the result of adjustment is reversed, i.e. shade 20 would get skewed toward the right rather than toward the left as it was before.
  • clip or clips 100 may be adhesively secured to extension 11, or in the event that roller 10 is formed of a ferrous metal, clip or clips 100 may be magnetically secured thereto.
  • the attachment means used to secure clip or. clips 100 to axial extension 11 allows for an easy relocation of clip or clips 100 in order to provide for fine adjustment of the resulting variation in the edge position 21 of shade 20.
  • Axial extension 11 appears to be a more convenient location for clip 100 than extension 14.
  • diametric pads 110 A variation of the above means is provided by diametric pads 110.
  • Pads 110 may be adhesively (or magnetically, if such means is applicable) secured to roller 10, preferably at areas providing the greatest effect such as along axial ridges 12 or 17.
  • the principle of operation of diametric pads 110 will be seen to be identical to that of clip 100, in that both serve to increase the effective diameter of that portion of the roller 10 to which they are secured.
  • Pads 110 can take variety of geometric shapes such as buttons, knobs etc., all serving the same function of increasing the effective radius of rotation of roller 10. Multiples of clips 100 and/or pads 110 may be used to provide a larger effective diameter if needed, and clips 100 and pads 110 may be used together if desired or needed.
  • Clips 100 of varying thickness may be provided, one of which is selected to satisfactorily accomplish the required adjustment. Additional means providing for the variation of effective diameter D of a roller 10 are shown in FIGURES 7 and 8. Clips 100 solve the problem in almost every instance; it has been found, two of such clips 100 are all that is necessary. Two clips 100 can be put on the opposite sides 15 and 16 of the extension 11 of roller 10 as a standard starting position. After shade 20 is placed into a window opening, positions of both clips 100 can be adjusted to such locations along extension 11 of roller 10 that optimize the objective adjustments set forth e.g., controlling internal gaps G 3 or G 4 versus external gaps G, or G 2 . The inventor found such a process to be fast, easy and highly effective.
  • Extension blade 120 will be seen to include a slot 121 , which slot 121 is formed to closely cooperate with roller extensions 11 or 14 of roller 10.
  • An outwardly extending blade 122 is provided opposite slot 121.
  • Blade 122 has lesser outward extension 123 to the left end 125 of extension blade 120, and a greater outward extension 124 to the right end 126 of blade 120. However, ends 125 and 126 of blade 120 can easily be reversed. If this was done, a greater extension 124 would be at the left end 15 of roller 10, and a lesser extension 123 would be at the right end 16 of roller 10. The resulting effect would be then similar to the effect of clip 100 of pad 110 being located on the left side of the extension 11 of roller 10, as in FIGURE 1.
  • the length may be shortened as indicated by phantom line 126a.
  • Such a modification of blade 120 offers an extra adjustment opportunity as blade 120 can now be moved from left to right along the extension 11 of roller 10 in a search for the best possible effect on correcting the rolling process of shade 20 on roller 10. Even with a modified, shorter length, blade 120 does not offer a complete flexibility of adjustment due to the monolithic construction of the extension blade 120.
  • an adjustable extension blade 130 may be used, as shown in FIGURE 8. Adjustable extension 130 is formed in a manner similar to that of blade extension 120, in that adjustable extension 130 also includes a longitudinal slot 131 to cooperate with roller extension 11 (or 14).
  • adjustable extension 130 provides a separate blade 133 adjustably affixed to the body 132 of extension 130 by means of blade slots 137 and securing screws 138.
  • securing screws 138 may be loosened and adjustable blade 133 positioned as desired, then screws 138 tightened to secure blade 133 in a fixed position relative to adjustable extension body 132.
  • adjustable extension 130 When installed upon a roller 10, adjustable extension 130 functions in the same manner as extension blade 120, serving to vary the respective widths on the left W L and on the right W R and, consequently, serving to vary the effective diameters of the left end 15 and the right end 16 of a roller 10 to which adjustable extension 130 is attached.
  • Adjustable blade 133 spans between ends 135 and 136 of blade 130, but can also be shortened as indicated by phantom line 136a, for an extra adjustment opportunity along extension 11 of roller 10 to search for a best possible control of the rolling process of shade 20 on roller 10.
  • pads 110 may be used to vary the effective diameter of a spring wound roller 18. While such spring wound rollers 18 are normally made of wood or perhaps a plastic material, in the event such a roller were to be formed of a ferrous material, such pads 110 could be magnetically secured. Other shapes may also be used in lieu of pads 110, such as the dots 111 disclosed in FIGURE 9, and a plurality of pads 110 or dots 111 may be stacked in order to achieve the desired effect.
  • FIGURE 9 further discloses the use of diametric adjustment screws 112 in such a spring wound shade roller 18.
  • screw heads 113 nearest the right end 182 of roller 18 serve to increase the effective diameter D 4 over the standard effective diameter D 3 of the shade roller 18 alone, thus providing the same benefits as discussed above in the modifications to the Hunter Douglas Silhouette roller 10.
  • screw heads 113 are relatively smooth in order to preclude damage to a shade secured to spring wound shade roller 18.
  • Procedure C Controlling the magnitude of external gaps by a torsional adjustment of the central housing.
  • Procedure B is primarily useful in controlling the magnitude of the internal gaps G 3 and G 4 .
  • the main problem will be with the external gaps G 1 or G 2 . This can be due to several reasons such as non-horizontal position of the lintel L, non-vertical position of wall edges W L or W RI or some error in the shade itself. Even a small error in the first rotation of the shade will be multiplied many times when the shade is fully drawn down. Sometimes, one of the gaps G, or G 2 will become zero, making a normal use of the shade very difficult.
  • FIGURE 10 shows a perspective view of the back side of the right upper corner of the window opening with the wall W R and lintel L and the shade 20 rolled up onto roller 10 with low bar 30 in its extreme upward position. Differential weight 33 of low bar 30 is secured in its desired position by the means of lock 34. Roller 10 is attached (through the front central housing 90, partially seen from the back) to lintel L by the means of mounting bracket 80. Right end plate 70 is secured to central housing 90.
  • the movable part 57 (not seen) of the roller actuating mechanism 50 is activated by cord 51 , causing rotation of roller 10 and movement of shade 20 up or- down.

  • mounting bracket 80 is permanently attached to lintel L by the means of screws 82 that go through oval holes 81 in bracket 80. This way, there is no gap between the flange 73 of the right end plate 70 and lintel L
  • FIGURE 10 shows two devices able to alter the position of the axis of rotation A of roller 10, and consequently the angular position of shade 20.
  • the first device is some form of wedge 140 inserted between the flange 73 of right end plate 70 (or between flange 63 of left end plate 60) and window lintel L, to maintain the gap between flange 73 of the right end 70 and lintel L. This gap is created by torsional adjustment applied manually to central housing 90. If the desired angular adjustment of the shade 20 is substantial, another wedge 160 is secured between the top 83 of mounting bracket 80 and lintel L. Wedge 160 is normally used together with wedge 140. Wedge 160 is needed when adjusting position of end plate 60 or 70 by means of wedge 140 alone is not able to bring the desired level of angular adjustment of shade 20.
  • FIGURE 11 discloses wedges 142 and 144 inserted between the flange 73 of a right end plate 70, and the adjacent lintel L. While the wedges 142 and 144 shown in FIGURE 11 are of circular cross section, other shapes may be used also. The circular cross section of wedges 142 and 144 provide for ease of insertion between flange 73 and the adjacent lintel L It will be seen that only one wedge 142 or 144 is needed to provide the necessary adjustment of end plate 70, but two are shown in order to make clear the point that various sizes may be provided and will serve the same function, depending upon the amount of angular variation and adjustment of space G 5 required. As noted above, any angular adjustment of either end plate 60 or 70 will affect the adjustment of roller 10, and thus shade 20, by means of the interconnecting housing 90 (not shown) between the two end plates 60 and 70.
  • Screw 146 or 148 are screws 146 or 148 as anchors for end plates 70 or 60. Screw 146 is outside the adjusted end plate 70 whereas screw 148 requires hole 147 to be first produced on end plate 70. It is important to assure that gap G 7 is comfortably close to zero as it would otherwise produce an unsightly view at the front of the window.
  • FIGURE 12 shows yet another alternative for torsional adjustment of central housing 90 through an adjustment of end plates 60 or 70.
  • a threaded hole 151 may be provided in the flange 63 or 73 of end plate 60 or 70, and an adjustment screw 150 provided therethrough.
  • Adjustment screw 150 includes an angularly adjustable pad 152, and an opposite adjustment grip 154. Threaded adjustment screw 150 inwardly or outwardly within flange hole 151 provides a continuous adjustment for end plate 60 or 70 (for details see FIG. 12a).
  • Locking nuts 156 may be added to protect adjusted position of plate 70 (or 60) from changing.
  • Procedure C 2 Angular adjustment of mounting brackets.
  • Mounting bracket 80 is secured to lintel L by the means of screws 82 that go through holes 81.
  • Angular adjustment of mounting bracket 80 is accomplished by wedge 160.
  • Wedge 160 has oval, expanded holes 161 to allow moving wedge 160 from left to right to adjust, within limits, the magnitude of the angular adjustment of wedge 160.
  • Angular adjustment of mounting bracket 80 should, normally, be accompanied by a corresponding angular adjustment of end plates 60 or 70, by any of the means previously recommended for such an adjustment, e.g., wedges 142 or 144 or screws 146 or 148.
  • the idea is to keep gap G 7 at point A close to zero, for a proper visual effect at the front of the central housing 90.
  • Bracket 160 Different versions of wedge 160 corresponding to varied magnitudes of the desired angular adjustments can be developed, so if a specific wedge 160 proves to provide an insufficient angular adjustment of the mounting bracket 80, a steeper wedge 160 can be used.
  • Another way to adjust the scale of the angular adjustment of bracket 80 is to reposition brackets 80 together with a corresponding wedge 160 from their original positions, as shown in FIGURE 15, to new positions marked by broken Iines, located closer to the middle of the lintel L. Such a procedure requires unscrewing screws 82 from the old position on the Lintel L and using them to screw brackets 80 together with corresponding wedges 160 into a new position.
  • Wedge 160 can be produced in many ways.
  • adjustable wedge 162 can be easily assembled from adhesive pads 110 and pad parts 115, as shown in FIGURE 16. Different geometric combinations of pads 110 and pad parts 115 can be assembled to accomplish such a steepness of wedge 162 that produces a desired level of angular adjustment of shade 20.
  • Oval holes 161 for screws 82 can easily be cut out in respective pads 110 or pad parts 115 as required.
  • Elementary pads 110 and pad parts 115 can preferably be produced from flexible material allowing for an easy formation of the desired geometric shape of wedge 162.
  • a variation of wedge 162, shown in FIGURE 16, is wedge 164 shown in
  • Wedge 164 is assembled from a required number of elementary prisms of adhesive pads 165 a, b, c, etc. to produce a desired steepness of wedge 164.
  • FIGURE 18 shows a simple and effective device that is able to angularly adjust position of central housing 90; it is a modified mounting bracket 170.
  • a bracket has a modified geometric shape such that it eliminates the need for any wedge 160 but alone accomplishes the effect identical to the combination of bracket 80 and wedge 160.
  • Modified bracket 170 can be designated in several versions corresponding to different magnitudes of the desired angular adjustments of central housing 90.
  • Modified bracket 170 has holes 171 for screws 172.
  • FIGURE 19 shows an alternative version to adjustable wedge versions shown in FIGURES 16 and 17.
  • Adjustable wedge 180 consists of two blades: lower blade 181 and upper blade 182, able to rotate around screw 183. Any necessary angular adjustment can be provided by placement of a small wedge 184. Size and position of wedge 184 determines the magnitude of the angular adjustment of mounting bracket 80.
  • Wedge 180 has oval hole 185 needed for main screw 186.
  • a larger size of hole 185 provides a useful opportunity for moving wedge 180 toward the front F of back B of the window opening for a better control of gap G 7 .
  • angular adjustment of end plate 70 (or 60) is needed. This can be accomplished by any of the means 142, 144, 146, 148 or 150. presented previously.
  • FIGURE 20 shows an adjustable wedge 190 that is similar to wedge 180 with the exception of the angle adjusting mechanism 194 replacing small wedge 184 to keep wedge 190 in its desired position.
  • Adjusting mechanism 194 is connected with upper blade 192 by the means of screw 197 around which mechanism 194 can rotate.
  • Mechanism 194 has keyways 198 corresponding with key 199 of lower blade 191. Similar to wedge 180, oval holes 195 are provided for screw 196.
  • FIGURE 21 shows an adjustable wedge 200 that is yet another variation of wedges 180 and 190, with the exception of the threaded adjustment screw 150 that is virtually identical in concept to the one used for adjustment of the end plates 60 or 70.
  • Threaded adjustment screw 150 goes through the top plate 281 of modified bracket 280 and adjacent low plate 201 end wedge 200. Adjusting screw 150 passes through a threaded hole 282 and is locked in the desired position by one or more locking nuts 156. Adjustment for screw 150, and therefore bracket 280 and any shade 20 which may be suspended therefrom, is provided by turning adjustment knob 154 in the desired direction to cause the back end 283 of bracket 280 to be displaced toward or away from lintel L.
  • bracket 280 together with wedge 200 were located toward the right end of the shade assembly, and the right edge of the shade was found to be too close to the window frame (gap G 2 becoming close to zero), lowering back end 283 of bracket 280 will angularly shift the assembly to cause the attached shade 20 to shift angularly away from the window wall W R .
  • similar adjustment may also on the left side of the shade assembly if external gap G,, became too close to zero.
  • low blade 201 can be permanently attached or combined with bracket 280 (or 80).
  • FIGURE 22 shows a combination 210 of bracket 280 and wedge 200 with the adjusting screw mechanism 250 similar to mechanism 150 shown in FIG. 21.
  • FIGURE 23 shows adjustable bracket 220, that is similar to bracket 210, with the exception of resistance spring 222 which makes adjusting screw mechanism 255 slightly different from mechanism 250 shown in FIGURE 22. Resistance from spring 222 needs to be overcome in case when for some reason angular adjustment of mounting 90 needs to be reduced. Thus, spring 222 works as an alternative, and probably a more flexible device than upper locking nut 256, see FIG. 22.

Abstract

L'invention concerne divers procédés et dispositifs de réglage visant à ajuster les angles et les côtés de certains types de stores de fenêtres. Ces divers réglages, destinés à corriger certains défauts d'ajustement desdits stores à l'intérieur des ouvertures de fenêtres, permettent de limiter les espaces extérieurs et intérieurs pouvant apparaître lors de l'enroulement ou du déroulement du store. Dans le procédé A, le mécanisme d'activation de l'enrouleur (50) est inversé pour passer d'une extrémité de l'enrouleur (10) à l'extrémité opposée. Le procédé B consiste à faire un réglage pour que le diamètre de l'enrouleur de store soit le même d'une extrémité à l'autre (10, 20, 30). Le procédé C présente divers dispositifs capables d'ajuster en termes de torsion le cadre du store (19, 20), dans le but de limiter les espaces extérieurs provoqués par les manoeuvres d'enroulement et de déroulement du store.
